The adjacency matrix for handwriting. (A) Hub, nodes, and edges of a simplified theoretical network. (B) Brain connectivity network of handwriting compared to typewriting in this experiment. (C) Hubs (in red, ≥ 4 departures/arrivals) and nodes (in black, ≤ 3 departures/arrivals) interacting between brain regions PL, PM, PR and CL, CM, CR show widespread theta/alpha connectivity patterns when writing by hand, but not when typing.
